Method, device and system for controlling power

Abstract

Embodiment of the invention provides a method, a device and a system for controlling power, relating to the communication field, and a power control performance of users accessed to a signal processing entity which cannot support a real time power control function can be improved; the method comprises the following steps: receiving a first signal sent by a first user by a signal processing entity which supports the real-time power control function, wherein the first user is an user accessed to the signal processing entity which cannot support the real-time power control function; receiving an indication which is sent by a control device so as to process a control channel signal of the first signal, and establishing a channel capable of loading the control channel signal of the first signal for the first user according to the indication; and processing the control channel signal of the first signal loaded on the channel and generating a detecting result for the control channel signal of the first signal loaded on the channel. An embodiment of the invention is applied to real time power control of the users.

Description

technical field [0001] The invention relates to the field of signal processing, in particular to a power control method, device and system. Background technique [0002] In a mobile communication system, due to the time-varying nature of air interface channel fading, the inner loop power control (inner loop power control) function of the signal processing entity adjusts the transmit power of the transmitting end in real time according to the signal-to-noise ratio of the signal at the receiving end, thereby ensuring that the receiving end The signal-to-noise ratio of the signal is stabilized at the set level to achieve the purpose of resisting channel fading and improving the demodulation performance of the receiving end. For the signal processing entities in the current system, different signal processing entities independently complete the inner-loop power control function of user signals connected to the entity, so as to compensate the influence of channel fading on user s...

Problems solved by technology

[0003] However, in the existing technology, the inventors found that due to the limitation of user processing resources at the receiving end or the constraints of processing load balance, the detection of different user signals in the system may be completed in different signal processing entities; in addition, due to the different signal processing entities Configuration or constraints between entities (such as: entities need to enjoy the gain of a certain function, etc.), some signal processing entities may not support real-time power control functions, resulting in an inner loop of user signals connected to the signal processing entity Power control cannot compensate for the loss of air interface channel fading by adjusting the transmit power of the sender in real time, which degrades the performance of power control
